DETAILED DESCRIPTION

[0022] 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.

[0023] Example 1

[0024] The existing dental handpieces are only tested for clamping force when they leave the factory and undergo regular maintenance, so that dental handpieces with unqualified clamping force can be repaired. During the period when the dentist uses the dental handpiece, the clamping force of the clamping needle 2 may be unqualified due to the impact of the dental handpiece or the failure of its clamping system. When the dentist uses the dental handpiece, the needle 2 is likely to fall off when performing oral treatment on the patient. Since the needle 2 falls off when rotating at high speed, it is dangerous and will cause safety hazards to the patient and the dentist. This embodiment provides a dental handpiece clamping force testing tool, such as Figure 1-Figure 2 As shown, it includes a shell 1 and a needle 2 installed at one end of the shell 1. A testing mechanism 3 for testing the clamping force is provided in the shell 1. Before using a dental mobile phone to perform oral treatment on a patient, the dentist can use the testing mechanism 3 to test the clamping force of the dental mobile phone to be used, thereby preventing the use of a dental mobile phone with unqualified clamping force for treatment, and facilitating the reduction of damage to the patient caused by a malfunction of the dental mobile phone during use.

[0025] The testing mechanism 3 includes a through slot 31 provided in the shell 1, a pull rod 32 can move in the through slot 31, and a pull rod 32 fixedly connected to the needle 2 is slidably connected in the through slot 31. When the needle 2 is connected to the dental mobile phone, the pull rod 32 is pulled to move, so that the needle 2 generates a pulling force on the dental mobile phone. A limit block 33 is provided on the surface of the pull rod 32, so that when the testing mechanism 3 is in an initial state, the limit block 33 contacts with the through slot 31 on the surface of the shell 1. A spring 34 is provided in the shell 1 and is sleeved on the surface of the pull rod 32. In the initial state, it is in a compressed state. When the pull rod 32 moves in the through slot 31, a moving block 35 at one end of the pull rod 32 will move with the pull rod 32 and compress the spring 34, so that the pull rod 32 is subjected to the force of the spring 34. When the force is equal to the qualified force and the needle 2 is not separated from the dental mobile phone, it proves that the dental mobile phone is in a normal state. Otherwise, it proves that the dental mobile phone cannot be used and needs maintenance. The housing 1 is provided with a moving block 35 fixedly connected to one end of the spring 34. The surface of the moving block 35 on one side of the pull rod 32 can be adjusted so that the distance between the moving block 35 and the inner wall of the housing 1 is shortened, that is, the length of the compressed spring 34. Before using the dental mobile phone for treatment, the dentist first inserts and fixes the needle 2 at one end of the long rod into the clamping system of the dental mobile phone. At the same time, the surface of the housing 1 is provided with a coating 36 for increasing friction. The dentist holds and pulls the housing 1 to make the long rod move in the through groove 31. At the same time, the moving block 35 at one end of the long rod compresses the spring 34, so that the spring 34 forms a pulling force on the long rod, and the pulling force acts between the needle 2 and the clamping system of the dental mobile phone, thereby achieving the purpose of detecting the clamping force of the dental mobile phone, which is convenient for the dentist to use the test mechanism 3 to test the clamping force of the dental mobile phone that needs to be used during work, thereby reducing the safety hazard of flying needles in the dental mobile phone.

[0026] A limit groove 37 is provided in the shell 1, and limit rods 38 sliding in the limit groove 37 are provided on both sides of the pull rod 32, and a marking scale 39 is provided on the surface of the pull rod 32 to indicate whether the clamping force is qualified. When the long rod moves in the through groove 31, the two ends of the spring 34 are respectively fixed to the inner wall of the shell 1 and the one side surface of the moving block 35. If the long rod rotates in the through groove 31, the spring 34 is prone to twisting, so that when the long rod slides in the through groove 31, the limit rod 38 moves along the limit groove 37, thereby preventing the long rod from rotating in the through groove 31, and when the long rod moves in the through groove 31 and completely exposes the marking scale 39, the pulling force of the spring 34 on the long rod is just equal to the qualified pulling force. In this state, the needle 2 is still not separated from the dental mobile phone, proving that the dental mobile phone is in normal working condition.

[0027] The surface of one end of the pull rod 32 is provided with a thread which is threadably connected to the moving block 35, and a slot 310 is provided at one end of the moving block 35. After the testing mechanism 3 has been used for a period of time, the spring 34 therein is prone to certain deformation, and the elastic force of the spring 34 can be adjusted without affecting the use, so that the pull rod 32 moves the same distance in the through groove 31, and the pulling force of the spring 34 on the pull rod 32 remains unchanged. At this time, the dentist can use a tool to insert the card slot 310 into the dental mobile phone, rotate the card slot 310, so that the moving block 35 slides on the surface thread of the pull rod 32, thereby changing the compression amount of the spring 34 in the initial state, which is conducive to the dentist using the detection mechanism to accurately detect whether the clamping force of the dental mobile phone is qualified.

[0028] Example 2

[0029] When the spring 34 of the detection mechanism is deformed, the dentist needs to use a tool to adjust the elastic force of the spring 34. When the tool is not stored properly, the dentist cannot adjust the elastic force of the spring 34, which is not conducive to the dentist adjusting the elastic force of the spring 34. When the marking ruler 39 is just exposed, the force of the spring 34 on the long rod is equal to the qualified force of the dental mobile phone clamping force. Based on Example 1, Figure 3 As shown, a sliding groove 311 is provided in the shell 1, and a push block 312 is slidably connected in the shell 1, and a limiting ring 313 sliding in the sliding groove 311 is provided on the surface of the push block 312, and a clamping block 314 clamped with the clamping groove 310 is provided at one end of the push block 312, and the clamping block 314 is made of a magnetic material, and an iron sheet 315 magnetically connected to the clamping block 314 is provided in the clamping groove 310. Since the clamping block 314 is a magnet, it will be adsorbed and connected with the clamping groove 310, so that the push block 312 and the moving block 35 are connected as a whole. At this time, the dentist can rotate one end of the push block 312 outside the shell 1, so as to rotate the moving block 35 to slide on the thread on the surface of the pull rod 32, so as to achieve the purpose of controlling and adjusting the deformation of the spring 34, and since the limiting ring 313 slides in the sliding groove 311, the push block 312 can move a certain distance in the shell 1 and dock with the moving block 35, so that the dentist can easily turn the push block 312 to adjust the elastic force of the spring 34.
