Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a percussion hammer. Background Art
[0002] As is known to all, a percussion hammer is an instrument used by neurologists to examine neuromuscular reflexes. However, the existing percussion hammer has a simple structure and a single function. It is simply a combination of a hammer body and a handle, and is unable to reduce the recoil force when medical staff hammer. Long-term use may easily cause damage to the hands of medical staff. At the same time, since the percussion force applied to patients of different severity is different, the existing percussion hammer is unable to adjust the intensity of the shock absorber accordingly, so when the percussion force is too heavy, it is easy to cause damage to the patient due to poor force control.
[0003] Therefore, it is necessary to make further improvements in the prior art. Utility Model Content
[0004] 1. Technical issues to be resolved
[0005] In view of the deficiencies in the prior art, the utility model provides a percussion hammer, which solves the problems mentioned in the above background technology.
[0006] (II) Technical solution
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a percussion hammer, comprising a hammer barrel, a connecting rod is provided on the outer wall of the hammer barrel, a handle is provided on the connecting rod, a limiting groove is provided inside the hammer barrel, a hammer rod is provided on the hammer barrel, a hammer head is provided at the bottom of the hammer rod, a limiting block is connected to the top of the hammer rod, a sliding rod is connected to the top of the limiting block, a plurality of slots are provided on the side wall of the sliding rod, a lifting ring is connected to the top of the sliding rod, a fixing frame is connected to the fixing frame, a rotating shaft is installed on the fixing frame, a blocking block is connected to the rotating shaft, a pressing handle is provided on the blocking block, and a spring is provided on the top of the limiting block.
[0008] Furthermore, the hammer rod and the slide rod are fixedly connected to the limit block, and the hammer rod, the slide rod and the limit block are slidably connected to the hammer barrel.
[0009] Furthermore, the hammer head is made of rubber.
[0010] Furthermore, each card slot matches with a card block.
[0011] Furthermore, the rotating shaft is fixedly connected to the clamping block, and the rotating shaft is connected to the fixing frame by rotation.
[0012] Furthermore, the side wall of the slide rod is provided with scales.
[0013] (III) Beneficial effects
[0014] Compared with the prior art, the utility model provides a percussion hammer, which has the following beneficial effects:
[0015] The percussion hammer pulls the slide bar through the lifting ring to compress the spring, and the slide bar is provided with a scale. The clamping block is fixedly connected to the rotating shaft and rotates on the fixed frame, so that the different heights of the slide bar are limited. By pressing the pressure handle, the hammer head can hammer downward under the action of the spring, which is convenient for the doctor to control the knocking force of the hammer head. The spring has a shock-absorbing effect, which is helpful to protect the doctor's hands. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In the figure: 1. hammer barrel; 2. connecting rod; 3. grip; 4. limit groove; 5. hammer rod; 6. hammer head; 7. limit block; 8. slide rod; 9. slot; 10. lifting ring; 11. fixing frame; 12. rotating shaft; 13. block; 14. pressing handle; 15. spring. DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-4The utility model discloses a percussion hammer, comprising a hammer barrel 1, a connecting rod 2 is arranged on the outer wall of the hammer barrel 1, a grip 3 is arranged on the connecting rod 2, the side wall of the grip is arranged with six faces to prevent the hand from slipping, a limiting groove 4 is arranged inside the hammer barrel 1, a hammer rod 5 is arranged on the hammer barrel 1, a hammer head 6 is arranged at the bottom of the hammer rod 5, the hammer head 6 is made of rubber, a limiting block 7 is connected to the top of the hammer rod 5, the limiting groove can limit the limiting block, a sliding rod 8 is connected to the top of the limiting block 7, and a scale is arranged on the side wall of the sliding rod 8, the hammer rod 5 and the sliding rod 8 are both connected to the limiting block 7 is fixedly connected, the hammer rod 5, the slide rod 8, and the limit block 7 are all connected to the hammer barrel 1 by sliding, the side wall of the slide rod 8 is provided with a plurality of slots 9, the top of the slide rod 8 is connected with a lifting ring 10, the top of the hammer barrel 1 is connected with a fixing frame 11, a rotating shaft 12 is installed on the fixing frame 11, a block 13 is connected to the rotating shaft 12, the rotating shaft 12 and the block 13 are fixedly connected, the rotating shaft 12 and the fixing frame 11 are connected by rotation, each slot 9 matches the block 13, a pressing handle 14 is provided on the block 13, and a spring 15 is provided on the top of the limit block 7.
