[0002] Dental handpiece is a commonly used medical device for oral treatment. Through high-speed rotation and different shapes of burs, it can position, drill, expand or even cut oral hard tissues. Blood, saliva, etc. are usually produced during oral surgery on patients. Infected substances seep into the interior of the mobile phone, and the parts are difficult to disassemble and clean. Long-term accumulation will affect the service life of the mobile phone and easily cause cross-infection
[0003] Existing dental handpieces are composed of a fuselage and a handpiece. The fuselage and the handpiece are detachably installed. However, the existing detachable method adopts threaded connection. However, due to the high-speed rotation and vibration during the working process, it is easy to cause the The connection of the machine head is loose

Embodiment Construction
[0034] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .
[0035] Such as Figure 1-4 As shown, a detachable dental handpiece with an anti-loosening safety device includes a body 3, a connecting seat 2, and a handpiece 1; the connecting seat 2 is fixed on the top of the body 3, and the handpiece 1 is detachable Connected to the connection seat 2;
[0036] The machine head 1 comprises a machine head shell 11, a split seat 12 fixed on the bottom of the machine head shell 11; the split seat 12 is detachably connected to the connecting seat 2; There is a limit slot 121 for limiting the activity of the push rod 34, such as Figure 4 shown;
[0037]The fuselage 3 includes a fuselage shell 31, a hollow mount 32, ...

The invention discloses a detachable dental handpiece with an anti-loosening safety device, which includes a body, a connecting seat, and a head; Reducer, ejector rod; the connecting seat is fixed on the reducer, and the reducer is fixed on the hollow mounting seat; the body shell is sleeved on the outer wall of the hollow mounting seat and the reducer; Socket; the ejector rod is provided with a radial boss of the ejector rod, the bottom end of the ejector rod is inserted into the socket of the hollow mounting seat, and protrudes outside the hollow mounting seat, and the radial boss of the ejector rod abuts against the socket Above, the top of the ejector rod is inserted into the socket of the connecting seat. This application sets an anti-loosening structure and a detachable structure, so that when the dental handpiece is in operation, the ejector rod extends into the limit slot and is not easy to slide out, preventing the connection part from loosening due to high-speed rotation, causing safety accidents, and at the same time facilitating the operation. Disassemble the main components for more efficient cleaning and maintenance.
