DETAILED DESCRIPTION
[0021] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a hammer with an adjustable handle, comprising a telescopic cylinder 1, an adjusting rod 2 passing through the interior of the telescopic cylinder 1, a hammer head 3 fixedly installed at the end of the adjusting rod 2, a handle 4 fixedly installed on the outer wall of the telescopic cylinder 1, the outer wall of the adjusting rod 2 is fixedly connected to one end of a compression spring 5, the other end of the compression spring 5 is fixedly connected to the inner wall of the telescopic cylinder 1, the compression spring 5 is in a compressed state, the elastic force of the compression spring 5 can make the adjusting rod 2 move toward the outside of the telescopic cylinder 1, the end hammer head 3 can be driven to extend by the adjusting rod 2, and an adjusting mechanism 6 is arranged inside the telescopic cylinder 1.
[0022] In this embodiment, an adjusting mechanism 6 is provided inside the telescopic cylinder 1. The fixing plate 64 is squeezed by the squeezing rod 67 in the adjusting mechanism 6, so that the clamping block 65 can rotate and move out of the inside of the clamping slot 66, so that the adjusting rod 2 can drive the end hammer head 3 to extend and adjust, and then the clamping block 65 is clamped in the inside of the clamping slot 66 to complete the adjustment of the hammer head 3 for convenient use. At the same time, the arc surface of the clamping block 65 moves to the right and is squeezed, so that the clamping block 65 can drive the fixing plate 64 to rotate so that the limit is released, so that the position of the hammer head 3 is reset and the adjustment is completed.
[0023] The above-mentioned adjusting mechanism 6 includes a fixing block 61, which is fixedly mounted on the outer wall of the adjusting rod 2, and a rotating rod 62 is rotatably connected to the inner wall of the fixing block 61. The outer wall of the rotating rod 62 is fixedly connected to one end of a torsion spring 63, and the other end of the torsion spring 63 is elastically connected to the inner wall of the fixing block 61. The elastic force of the torsion spring 63 can make the fixing plate 64 drive the clamping block 65 to rotate and reset and be clamped in the inside of the clamping groove 66, so as to conveniently complete the use of the extension of the hammer head 3. A fixing plate 64 is sleeved on the outer wall of the rotating rod 62, and a clamping block 65 is fixedly mounted on the outer wall of the fixing plate 64. One side of the clamping block 65 is set in an arc shape. The clamping block 65 on the outer wall is driven to move to the right by the fixing plate 64 so that the arc surface is squeezed, so that the clamping block 65 can drive the fixing plate 64 to rotate so that the limit is released, which is convenient for adjustment. 1 is provided with a card slot 66, and the card slot 66 is arranged in an array on the telescopic cylinder 1. A card block 65 is carded inside the card slot 66, and the size of the card slot 66 is adapted to that of the card block 65. An extrusion rod 67 runs through the inside of the adjusting rod 2, and the extrusion rod 67 is arranged in a bent shape. The end of the extrusion rod 67 is located above the fixed plate 64, and the outer wall of the fixed plate 64 is squeezed by the right end of the extrusion rod 67. Through the squeezing, the fixed plate 64 can drive the card block 65 to rotate out of the card slot 66 so that the limit is released. A return spring 68 is sleeved on the outer wall of the extrusion rod 67, and one end of the return spring 68 is fixedly connected to the outer wall of the extrusion rod 67, and the other end of the return spring 68 is fixedly connected to the inner wall of the adjusting rod 2. The elastic force of the return spring 68 can reset the extrusion rod 67 and no longer squeeze the fixed plate 64.
[0024] In this embodiment, when the adjusting rod 2 needs to be extended, the squeezing rod 67 is first pushed to the right, and then the outer wall of the fixing plate 64 is squeezed by the right end of the squeezing rod 67, and then the fixing plate 64 drives the card block 65 to rotate and move out of the card slot 66 through squeezing, and the limit is released. The elastic force of the compression spring 5 makes the adjusting rod 2 move toward the outside of the telescopic cylinder 1, and then the adjusting rod 2 drives the end hammer head 3 to extend. After the adjustment is completed, the squeezing rod 67 is released and the reset spring 68 is used to reset the squeezing rod 67 and no longer squeeze the fixing plate 64. Finally, the fixing plate is pressed by the elastic force of the torsion spring 63. When the position of the hammer head 3 needs to be shortened, the hammer head 3 is pushed toward the telescopic tube 1, and the adjusting rod 2 drives the fixing plate 64 on the outer wall of the fixing block 61 to move rightward, and then the fixing plate 64 drives the fixing block 65 on the outer wall to move rightward so that the arc surface is squeezed, so that the fixing block 65 drives the fixing plate 64 to rotate so that the limit is released, and then the adjusting rod 2 moves normally toward the inside of the telescopic tube 1 to complete the adjustment, and then the resetting of the position of the hammer head 3 is completed for convenient adjustment.
[0025] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
