Detailed Description

The principles and features of the present invention will be described with reference to the drawings, which are provided for illustration only and are not intended to limit the scope of the invention.

As shown in fig. 1-7, a novel leather drum comprises a drum surface 1 and a clamping component 8, wherein a handle 2 is fixed at the middle position of one end of the drum surface 1, the inside of the handle 2 is movably connected with a central shaft 3, connecting pieces 4 are installed at two ends of the central shaft 3, the other ends of two groups of connecting pieces 4 are respectively provided with the other end of a rack 5, a handle 6 is fixed on the side surface of the rack 5, a blade 7 is installed on the rack 5, the clamping component 8 is installed on the side surface of the handle 2, and the clamping component 8 is located inside the starting end of the drum surface 1.

The clamping assembly 8 comprises push rods 84, two groups of push rods 84 are arranged in parallel, a first transverse shaft 85 and a second transverse shaft 86 are fixed between the two groups of push rods 84 in parallel, and the first transverse shaft 85 is connected with the handle 2 through a first spring 81. The push rod 84 and the handle 2 are connected through the first spring 81, so that when one end of the push rod 84 is fixed, one end of the push rod 84 is not influenced to move, the motion track of the push rod 84 is not limited to be linear, and a fixed lug 87 of the push rod 84 can move in the sliding groove 82.

The clamping assembly 8 further comprises a convex block 87, the inner walls of the two sides of the starting end of the drumhead 1 are provided with a sliding groove 82 and a clamping groove 83, the convex block 87 is fixed on the outer side of the push rod 84, and the convex block 87 is arranged inside the sliding groove 82 and the clamping groove 83. The locking groove 83 is arc-shaped, the projection 87 is cylindrical, the cross section diameter of the projection 87 is the same as that of the locking groove 83, and the projection 87 and the locking groove 83 form a clamping structure. The push rod 84 is controlled to move, so that the projection 87 moves in the sliding groove 82, after the projection 87 moves and falls into the clamping groove 83, the push rod 84 is fixed under the limit of the clamping groove 83 and the first spring 81, the push rod 84 is continuously pushed, the first spring 81 is stretched, the projection 87 moves in the sliding groove 82, and the push rod 84 can be reset.

Example 1: when the skin of a patient is cut, a user can hold the handle 2 with a hand, four fingers are placed between the first transverse shaft 85 and the second transverse shaft 86 to complete the control of the drumhead 1 and the clamping assembly 8, the second transverse shaft 86 is pushed, at the moment, the first spring 81 is stretched, the lug 87 arranged on the side surface of the push rod 84 moves inside the sliding groove 82, when the lug 87 falls into the clamping groove 83, the push rod 84 is limited under the action of the first spring 81, so that the position of one end of the push rod 84 cannot move, and the position fixing of the push rod 84 is completed.

The clamping assembly 8 further comprises an inner clamping plate 88, the inner clamping plate 88 is connected with the push rod 84 through a bolt 810, and connecting shafts 89 are fixed at two ends of the lower half section of one side of the inner clamping plate 88 far away from the push rod 84. The clamping assembly 8 further comprises an outer clamping plate 811, a groove is formed in the middle of one side of the outer clamping plate 811, a connecting groove 812 is formed in two ends of one side of the outer clamping plate 811, a connecting shaft 89 is arranged inside the connecting groove 812, and the outer clamping plate 811 and the inner clamping plate 88 are connected through a plurality of groups of second springs 813. Through the cooperation of connecting axle 89 and spread groove 812, make and accomplish the equipment between interior splint 88 and the outer splint 811 to with the help of the recess, make outer splint 811 can rotate in interior splint 88 one side, change the contained angle between interior splint 88 of both and the outer splint 811, be convenient for shift out outer splint 811 from drum-head 1 is inside.

The inner plate 88 is partially positioned inside the groove, the inner plate 88 and the outer plate 811 constitute a rotating structure, and the second springs 813 are fixed at equal distances between the inner plate 88 and the outer plate 811. The second spring 813 is fixed between the inner plate 88 and the outer plate 811, so that the distance between the inner plate 88 and the outer plate 811 is kept within a certain range, the position and angle of the outer plate 811 are not changed, the distance between the inner plate 88 and the outer plate 811 can be changed under the action of a large external force, and the outer plate 811 can be moved inside and outside the drumhead 1.

Example 2: when the skin of cutting the patient carries out the centre gripping fixedly, through promoting push rod 84, make outer splint 811 and drumhead 1 contact the back, compress second spring 813, make outer splint 811 shift out from the drumhead 1 is inside, until inner splint 88 and outer splint 811 shift out from the drumhead 1 is inside completely, at this moment, push rod 84's rigidity, under the effect of second spring 813, outer splint 811 is close to inner splint 88, and then make outer splint 811 and the outside laminating of the initiating terminal of drumhead 1 mutually, thereby it is fixed to carry out the centre gripping to the initiating terminal of cutting skin, make the skin laminating can not break away from on drumhead 1, conveniently roll drumhead 1, continue to cut skin.

The working principle is as follows: the user can hold the handle 2 by hand, and the four fingers are placed between the first horizontal shaft 85 and the second horizontal shaft 86 to complete the control of the drumhead 1 and the clamping assembly 8, by pushing the second horizontal shaft 86, at this time, the first spring 81 is stretched, the projection 87 arranged on the side of the push rod 84 moves inside the sliding groove 82, so that the outer clamping plate 811 moves out of the drumhead 1 until the inner clamping plate 88 and the outer clamping plate 811 completely move out of the drumhead 1, at this time, when the projection 87 falls into the clamping groove 83, and the push rod 84 is limited under the action of the first spring 81, so that the position of one end of the push rod 84 does not move, and the position fixing of the push rod 84 is completed, and under the action of the second spring 813, the outer clamping plate 811 approaches the inner clamping plate 88, so that the outer clamping plate 811 is attached to the outer side of the starting end of the drumhead 1, thereby clamping and fixing the starting end of the cut skin to be attached to the drumhead 1 without being separated, the convenient drum-head 1 that rolls continues to cut skin, accomplish the back to patient's skin cutting, when needing to take off skin from drum-head 1, through continuing to promote a section distance of push rod 84, make first spring 81 tensile, let lug 87 shift out from draw-in groove 83 is inside, make lug 87 move in spout 82 is inside, when first spring 81 resets, first spring 81 pulls push rod 84 and moves, make lug 87 move to the end of spout 82, and simultaneously, push rod 84 resets, pull interior splint 88, at this moment, outer splint 811 outwards rotates certain angle and moves the inboard of drum-head 1 through the drum-head 1 outside at last, make the one end of skin lose the injecture, thereby take off skin from drum-head 1.
