A workbench 2 is fixedly connected to the top of the base 1. A slider 3 is slidably connected to the inner wall of the workbench 2. An inclined surface is provided on the slider 3. When the inclined surface is compressed, the slider 3 moves forward. A positioning plate 5 is hinged to the top of the slider 3 via a hinge rod 4. Two sets of positioning plates 5 are provided, and the two sets of positioning plates 5 work together to position the guardrail. The outer wall of the slider 3 is elastically connected to the workbench 2 via a movable spring 7. An adjustment mechanism is provided on the inner wall of the workbench 2. A bracket 10 is fixedly connected to the top of the workbench 2. An electric telescopic rod 11 is provided at the top of the bracket 10. The electric telescopic rod 11 is a device that can achieve telescopic movement of the rod body by being driven by a motor. The electric telescopic rod 11 is powered by a motor, and its rotational motion is converted into linear motion through a transmission mechanism. This is existing technology and will not be elaborated further. The lower end of the electric telescopic rod 11 is provided with a punch head 15, and the bottom end of the electric telescopic rod 11 is provided with a replacement component. The adjustment mechanism includes a pull rod 6. The left end of the pull rod 6 is a rectangular block, and the right end is a cylinder. When the pull rod 6 moves to the right, the rectangular block will contact and press the inclined surface of the slider 3. A locking block 8 is inserted into the outer wall of the pull rod 6. The outer wall of the pull rod 6 has multiple sets of slots. The locking block 8 is initially inserted into the slots. The outer wall of the locking block 8 is elastically connected to the worktable 2 through a moving spring 9. The pull rod 6 passes through and slides on the inner wall of the worktable 2. The inner wall of the worktable 2 has slots corresponding to the pull rod 6, allowing the pull rod 6 to move left and right.

[0036] Reference Figure 1 , Figure 6 and Figure 7 The replacement component includes a connecting post 12, with a sliding insert 13 connected to the inner wall of the connecting post 12. The inner wall of the connecting post 12 has a slot corresponding to the insert 13, allowing the insert 13 to move back and forth. Two sets of insert 13 are provided, elastically connected by a positioning spring 14. When the two sets of insert 13 approach each other, the positioning spring 14 is compressed. Upon resetting, the elastic force of the positioning spring 14 separates the two sets of insert 13, fixing the connecting post 12. Connected to the bottom end of the electric telescopic rod 11, the connecting post 12 is inserted into the top end of the punch head 15. The punch head 15 has a slot corresponding to the connecting post 12. The connecting post 12 is initially inserted into the slot. The insert block 13 is inserted into the inner wall of the punch head 15. The punch head 15 has a slot corresponding to the insert block 13, so that the insert block 13 can be inserted into the slot. The punch head 15 is a tool component used for punching holes in materials (such as metal, plastic, leather, etc.).

[0037] Reference Figures 3-5The top of slider 3 is hinged to one end of hinge rod 4, and the other end of hinge rod 4 is hinged to the bottom end of positioning plate 5. Since the length of hinge rod 4 is fixed, when slider 3 moves forward with one end of hinge rod 4, the other end of hinge rod 4, along with the two sets of positioning plates 5, moves closer together. When slider 3 moves backward with one end of hinge rod 4, the other end of hinge rod 4, along with the two sets of positioning plates 5, separates from each other. The outer wall of slider 3 is fixedly connected to one end of movable spring 7, and the other end of movable spring 7 is fixedly connected to the inner wall of the rear end of worktable 2. When slider 3 moves forward, movable spring 7 is stretched. When pull rod 6 does not obstruct slider 3, the reverse elastic force of movable spring 7 will pull... The movable slider 3 moves backward, and the outer wall of the locking block 8 is fixedly connected to one end of the moving spring 9. The other end of the moving spring 9 is fixedly connected to the inner wall of the rear end of the worktable 2. When the locking block 8 moves backward, the moving spring 9 is compressed. When resetting, the elastic force of the moving spring 9 is used to reset the locking block 8. The locking block 8 is slidably connected to the right side wall of the worktable 2. The worktable 2 has a slot corresponding to the locking block 8, allowing the locking block 8 to move back and forth. The positioning plate 5 passes through and is slidably connected to the inner wall of the worktable 2. The worktable 2 has a slot corresponding to the positioning plate 5, allowing the positioning plate 5 to move left and right. The front end of the pull rod 6 contacts the outer wall of the slider 3.

[0038] Working principle: When positioning the guardrail, the operator should first move the locking block 8 backward. The backward movement of the locking block 8 will compress the moving spring 9. When the locking block 8 separates from the slot on the pull rod 6, the operator should pull the pull rod 6 to the right. The pull rod 6 moving to the right will compress the inclined surface of the slider 3, causing the slider 3 to move forward. The forward movement of the slider 3 will stretch the movable spring 7. When the slider 3 moves forward with one end of the hinge rod 4, the other end of the hinge rod 4 will bring the two sets of positioning plates 5 together. The two sets of positioning plates 5 will position the guardrail. At this point, the locking block 8 will align with the slot on the pull rod 6. The operator can then release the locking block. 8. Using the elastic force of the movable spring 9, the locking block 8 is inserted into the slot of the pull rod 6 to limit the two sets of positioning plates 5. When it is necessary to increase the distance between the positioning plates 5, move the pull rod 6 to the left. When the pull rod 6 no longer blocks the slider 3, it moves the slider 3 backward under the action of the movable spring 7. When the slider 3 moves backward with one end of the hinge rod 4, the other end of the hinge rod 4 will separate the two sets of positioning plates 5. At this time, let the locking block 8 be inserted into the slot of the pull rod 6 to limit the positioning plate 5. If it is necessary to position the guardrail, simply repeat the above operation steps.

[0039] When the punch head 15 needs to be replaced, press the insert block 13 with your hand. The two sets of insert blocks 13 will move closer together and squeeze the positioning spring 14. When the insert block 13 separates from the slot on the punch head 15, remove the punch head 15 downwards with your hand. Then release the insert block 13 with your hand. Under the elastic force of the positioning spring 14, the two sets of insert blocks 13 return to their initial state. When the punch head 15 needs to be installed, press the insert block 13 with your hand. When the insert block 13 no longer obstructs the punch head 15, align the punch head 15 with your hand and insert it into the bottom end of the connecting post 12. Release the insert block 13 with your hand. The insert block 13 returns to its initial state and limits the obstruction of the punch head 15. If the punch head 15 needs to be replaced again, simply repeat the above operation steps.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
