Detailed Description

The following detailed description of the technical solutions according to the embodiments of the present invention will be given with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.

Referring to fig. 1, the door-type nail spreader includes a left handle 100, a right handle 200, a left jaw 110 and a right jaw 210 movably connected through a rotation shaft, the left handle 100 and the left jaw 110 are integrally formed, the right handle 200 and the right jaw 210 are integrally formed, a clamping groove 300 is formed on the surfaces of the left jaw 110 and the right jaw 210 respectively in opposite directions, two clamping grooves 300 clamp a cross arm 410 of a door-type nail 400, and two vertical arms 420 of the door-type nail 400 respectively support against opposite outer side surfaces of the left jaw 110 and the right jaw 210.

In this technical scheme, during the use, at first separate two handles, because left handle and left jaw are located same one side and integrated into one piece, right handle and right jaw are located same one side and integrated into one piece, so two handles are laminated when separating, load into the draw-in groove with door nail xarm this moment, then compress tightly two handles, two keep in two vertical arms of door nail respectively to support the lateral surface when separating, prop up two vertical arms of door nail open, then put into the hole that fracture line both ends were beaten into in advance with door nail is quick, then only need withdraw the device, because the automatic resilience of door nail realizes the pressurization of broken line department, medical personnel's operation efficiency has been improved, the time of operation has been reduced, patient's misery is alleviateed.

Further, the inside surfaces of the two vertical arms 420 of the portal nail 400 are uniformly formed with barbed teeth 430, respectively.

In this technical scheme, can prevent that the door nail from deviating from.

Further, the two vertical arms 420 of the gate-type nail 400 are bent toward each other.

In the technical scheme, the rebound pressurization is conveniently realized after the door-shaped nails are unfolded.

Further, a spring piece 500 is provided between the left handle 100 and the right handle 200.

In the technical scheme, the two handles are conveniently separated, and the operation is convenient.

Further, a locking lever 600 is provided between the left handle 100 and the right handle 200, the locking lever 600 protrudes from the left handle 100 and penetrates the right handle 200, a stopper 610 locking the left handle 100 is formed on the surface of the locking lever 600, and the locking lever 600 is rotatably installed to the left handle 100.

In this technical scheme, can be so that strut the locking of locking lever between the door nail, can not hard in inserting the preformed hole with the door nail like this, also reduced occupation space after locking when this device does not use simultaneously. It should be noted that the locking lever may also protrude from the right handle, and should be within the scope of the present application.

Further, a guide sleeve 700 is formed at the tail of the left handle 100, and two parallel guide holes 710 are formed on the surface of the guide sleeve 700. The guide hole extension line forms an included angle with the extension line of the left handle 100.

In this technical scheme, because the door nail needs to punch at fracture line both ends before inserting, should two holes side by side can cooperate the drill bit to punch into parallel screw hole at fracture line both ends to because form an contained angle between guiding hole extension line and the left handle extension line, prevented the interference when handle is to punching.
