The utility model adopts the technical proposal that: a safety pawl lock of a nail shooting fastening tool comprises a support, a lifting wheel, a firing pin connected in a movable groove of the support, a pawl rotationally connected to a rotating column of the support, a sliding block with one end rotationally connected to a connecting shaft of the pawl and an elastic piece, wherein the guide column is arranged on the support, the sliding block is slidably connected to the guide column through a movable long groove in the sliding block, one end of the elastic piece is connected with the guide column, and the other end of the elastic piece is connected with the inner wall of the movable long groove.
Furthermore, a screw hole is formed in the guide pillar, and a screw is connected to the screw hole in a threaded manner.
Furthermore, the slider is provided with a connecting hole which is rotationally connected with the connecting shaft.
Further, the elastic member is a spring.
Furthermore, guide surfaces which are attached to two sides of the movable long groove are arranged on two sides of the guide post.
Furthermore, guide plates are arranged on the brackets at two sides of the sliding block.
The utility model has the advantages that: the utility model discloses a slider relies on the elastic component to work, can not receive magnetic interference, helps improving the stability of slider work, improves the safety in utilization and the stability of penetrating nail fastening tool, and in addition, the elastic component can play the cushioning effect, but also can provide power for the pawl return.
In addition to the above-described objects, features and advantages, the present invention has other objects, features and advantages.
The present invention will be described in further detail below with reference to the accompanying drawings.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic diagram of the separation of the slider and the bracket.
In FIGS. 1-2: 1. a support; 2. a lifting wheel; 3. a movable groove; 4. a striker; 5. turning the column; 6. a pawl; 7. a slider; 8. an elastic member; 9. a connecting shaft; 10. a guide post; 11. a movable long slot; 12. a screw hole; 13. a screw; 14. connecting holes; 15. a guide surface; 16. a guide plate.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.
The utility model provides a safe pawl lock of shooting nail fastening tool.
In this embodiment, referring to fig. 1-2, the safety pawl lock of the nail shooting fastening tool includes a bracket 1, a lifting wheel 2, a striker 4 connected in a movable groove 3 of the bracket, a pawl 6 rotatably connected to a rotary column 5 of the bracket, a slider 7 with one end rotatably connected to a connecting shaft 9 of the pawl, and an elastic member 8, wherein the bracket is provided with a guide column 10, the slider is slidably connected to the guide column through a movable elongated groove 11 on the slider, one end of the elastic member is connected to the guide column, and the other end of the elastic member is connected to an inner wall of the movable elongated groove.
Among the above-mentioned technical scheme, the slider relies on the elastic component to work, can not receive magnetic force interference, helps improving the stability of slider work, improves and penetrates nail fastening tool's safety in utilization and stability, and in addition, the elastic component can play the cushioning effect, but also can provide power for the pawl return.
The specific working principle is as follows: when the lifting wheel rotates, after the unlocking step on the lifting wheel abuts against the sliding block, the elastic force of the elastic piece is overcome to enable the sliding block to slide, and therefore the pawl is driven to rotate to complete unlocking. In addition, after the unlocking step is far away from the pawl, the sliding block is pulled back under the elastic force of the elastic piece, so that the pawl is driven to return to complete the locking action with the firing pin, and the principle can refer to a safety pawl lock of the handheld nail shooting fastening tool disclosed in application number 2021227481744. Above in-process, the elastic component can play the cushioning effect, can provide power for the slider return simultaneously.
