Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Example one

As shown in fig. 1 to 5, the back-pushing type utility knife includes a housing with a knife outlet at the front end, a knife clamp 3 is fixedly inserted in the housing, a base 4 and a blade 5 are installed in the knife clamp 3 from back to front, a clamping seat 401 is convexly arranged on one side of the base 4, a communication clamping position is arranged between the inner side of the clamping seat 401 and the base 4, an elastic part 6 is embedded in the communication clamping position, the elastic part 6 elastically abuts against the inner wall of the knife clamp 3, a push-pull slideway is arranged on one side of the knife clamp 3, a plurality of clamping grooves 301 are symmetrically and concavely arranged on the upper edge and the lower edge of the push-pull slideway, the elastic part 6 and any pair of clamping grooves 301 form an elastic clamping connection, a sliding seam 101 located on one side of the knife back of the back-pushing type utility knife is opened on the housing, a side plate 7 extending into the sliding seam 101 is arranged on the clamping seat 401, and a back-pushing button 8 located outside the sliding seam 101 is connected on the side plate 7.

The elastic piece 6 comprises a vertical strip-shaped U-shaped part 601, two sides of the U-shaped part 601 are provided with elastic pieces 602 which extend outwards symmetrically, and an elastic included angle is formed between the two elastic pieces 602. The upper end and the lower end of the U-shaped part 601 are correspondingly inserted into any pair of clamping grooves 301 to form elastic clamping connection; the elastic sheet 602 abuts against the inner wall of the tool holder 3 through the outer end edge.

The angle of the elastic included angle is changed by opening and closing the two elastic sheets 602, so that the overall thickness of the elastic part 6 is changed, the upper end and the lower end of the U-shaped part 601 enter the clamping groove 301 for clamping or are separated from the clamping groove 301 to move freely, and the switching operation of clamping and sliding is realized.

A side hole is formed in the base 4, a clamping jaw 701 is arranged on the inner wall of the side plate 7 in a protruding mode, and the clamping jaw 701 is clamped and embedded into the side hole to form clamping and positioning. Through the clamping structure, the side plate 7 can be fixedly connected with the base 4, and the assembling and disassembling operation can be facilitated.

The inner side of the claw 701 is provided with a groove, and the outer wall of the U-shaped part 601 is embedded into the groove to form positioning clamping. The claw 701 and the U-shaped part 601 are fixed through clamping fit, namely the back push button 8 and the side plate 7 are connected with the elastic part 6, so that the elastic part 6 is prevented from being separated from a communication clamping position.

The top surface of the back push button 8 is provided with anti-skid grains which are specifically a plurality of parallel-arranged grooves. The friction force between the finger and the finger is increased through the arrangement of the anti-slip grains, so that the pushing effect is better.

The back pushing type utility knife has the following use modes:

the back push button 8 at the back side is pressed by the left hand or the right hand and pushed forwards, under the action of the forward pushing force, the elastic piece 6 automatically and elastically deforms to be separated from the clamping groove 301, so that the blade 5 moves forwards along the tool holder 3 and extends out of the tool nose, the forward pushing action is stopped, and the elastic piece 6 automatically restores the original shape and is clamped into the clamping groove 301 at the corresponding position. The user cuts the article through the blade tip while keeping pressing the back push button 8. After the use, the back push button 8 is pressed to pull back the blade 5 for resetting.

Example two

Based on the first embodiment, the present embodiment specifically includes:

as shown in fig. 1 to 3, a positioning pin 402 is protruded from the base 4, a positioning hole is opened at the tail end of the blade 5, and the positioning hole is sleeved on the positioning pin 402, so that the blade 5 is connected with the base 4. Due to the limitation of the long and narrow flat cavity in the tool holder 3, after the blade 5 is connected with the base 4, the blade 5 does not have a moving space for displacement in other directions, and can only be driven by the base 4 to perform push-pull action.

The casing includes shell body 1 and tail-hood 2, and the rear end of shell body 1 is the assembly opening, and the periphery of assembly opening sets up the assembly step, and the one end of tail-hood 2 is uncovered for the assembly, cup joints tail-hood 2 on the assembly opening through the assembly is uncovered, makes the open mouth of assembly lean on the top to assemble the step formation fixed equipment. Frictional contact is formed between the inner wall of tail-hood 2 and the outer wall of assembly opening, is interference fit between the two promptly to realize the fixed equipment of both through frictional force, unless demolish tail-hood 2 under the effect of artificial outer pulling out.

The inside of tail-hood 2 sets firmly baffle 201, sets up spacing step on the border of baffle 201, and back of the body pushes away button 8 and slides to the limit inner and make 7 borders of curb plate lean on the spacing step formation spacing fixed of baffle 201. Through the blocking effect of the baffle 201, the limiting and fixing of the inward movement of the blade 5 are realized, and the phenomenon that the U-shaped part 601 is separated from the clamping groove 301 due to the excessive backward movement of the blade 5 is avoided.

The clamping groove 301 at the tail end is an initial groove, and the spacing distance between the initial groove and the adjacent clamping groove 301 is greater than the spacing distance between the rest clamping grooves 301. When the U-shaped portion 601 is inserted into the initial slot, which means that the blade 5 has been retracted to the extreme position, the side plate 7 is just abutted against the stop plate 201.
