The structure of the supporting frame 120 is not limited to the structure of the first plate portion 121 and the second plate portion 122.

Example 2

As shown in fig. 12 and 13, the present embodiment is different from embodiment 1 in that the front surface 116 of the guide block 113 is provided with a groove 215, and a row of second slots 214 is provided on both sides of the groove 215. The number of the second tooth grooves 214 in each row is multiple, and the second tooth grooves are arranged along the nail-out direction. The number of the second teeth grooves 214 may be determined according to the moving distance of the support bracket 120.

As shown in fig. 14, 15 and 16, the support bracket 120 includes a first plate body portion 121 and a second plate body portion 122 as described in embodiment 1. The second plate portion 122 in this embodiment is not provided with the lugs 127. In the present embodiment, a protective case 220 is provided on the second plate body portion 122. The protective case 220 is provided with a through hole 221. The through hole 221 extends in a direction perpendicular to the nail-ejecting direction, penetrates the protective casing 220, and communicates with the accommodating hole 125. A shaft pin 222 is inserted into the protective case 220. The shaft pin 222 is movably arranged in a direction perpendicular to the nail ejecting direction. A movable connecting block 223 is disposed in the through hole 221. Attachment block 223 fits over pin 222. Connecting block 223 is provided with a convex tooth 224. The number of teeth 224 may be one or plural. In the example shown, the teeth 224 are arranged in plural in the nail ejection direction. The shaft pin 222 is sleeved with a compression spring 225. A compression spring 225 is located within the bore 221 with one end abutting the protective shell 220 and the other end abutting the connecting block 223.

The rest of the structure is the same as in example 1.

As shown in fig. 17, in the present embodiment, when in use, the plurality of teeth 224 are respectively fitted into the plurality of second grooves 214, so that the connecting block 223 is engaged with the guide block 113, and the support frame 120 is connected to the nail ejection portion 111. The elastic force of the compression spring 225 maintains the connection block 223 in this state. The support 120 cannot move in the nail-ejecting direction at this time. When the connection position of the support bracket 120 on the nail gun 110 needs to be changed, the shaft pin 222 is pushed, the connecting block 223 moves perpendicular to the nail-out direction, and the convex tooth 224 moves out of the second tooth groove 214 until the convex tooth is opposite to the groove 215. Due to the arrangement of the groove 215, the connecting block 223 has no engagement relation with the guide block 113, and the support frame 120 is disconnected from the nail-ejecting part 111. The compression spring 225 is compressed to generate a greater elastic force. At this time, the support stand 120 may move in the nail ejection direction or a direction opposite to the nail ejection direction to change the relative position with the nail gun 110. After the support frame 120 is moved to the right position, the pushing force on the shaft pin 222 is released, the connecting block 222 is reset under the elastic force of the compression spring 225, and the plurality of convex teeth 224 are re-embedded into the plurality of second tooth grooves 214.

In this embodiment, the compression spring 225 is one of the embodiments of the second elastic device, and other components having the same function may be used instead. The groove 215 is formed on one side of the second tooth groove 214, and the convex tooth 224 is opposite to the groove 215 after moving out of the second tooth groove 214, so that interference generated after the convex tooth 224 moves out of the second tooth groove 214 can be avoided, and the normal movement of the connecting block 223 is prevented from being influenced. As an alternative embodiment, it is also possible to provide only one row of second grooves 214 on one side of the groove 215.

In this embodiment, connection block 223 is one embodiment of a connection member.

Cam 330 is integrally formed with handle 331.

The rest of the structure is the same as in example 1.

In the present embodiment, when the cam 330 rotates, the urging force of the cam against the guide block 113 changes. When the urging force of the cam 330 against the guide block 113 is sufficiently large, the support stand 120 can be held at a desired attachment position. The rotating cam 330 reduces its urging force against the guide block 113, and the support frame 120 can move along the nail ejection portion 111. Until moved to the proper position, the cam 330 is rotated to push against the guide block 113, and the support 120 is held in that position.

In this embodiment, the cam 330 is one of the embodiments of the link.
