Abstract
Description
Technical Field
[0001] The utility model relates to a matching tool for insect experiment and research, in particular to an insect dissection pen. Background Art
[0002] Insect dissection is an important means of studying the internal organs of insects. Due to the small size of insects, it is necessary to use insect dissection needles with smaller diameters to dissect insects.
[0003] The insect dissecting needle in the prior art includes a needle tip and a pen body for the staff to hold. The diameter of the pen body is larger than the diameter of the pen tip. However, for an adult, the diameter of the pen body is still relatively thin, and it is not easy for the staff to hold it. Therefore, a problem with the prior art is that since the pen body of the insect dissecting needle is thin, it is not easy for the staff to hold it, which leads to inaccurate operation of the pen tip. Utility Model Content
[0004] The utility model aims to provide an insect dissecting pen to solve the technical problem that the insect dissecting needle pen body in the prior art is too thin to be easily held by a worker.
[0005] In order to solve the above technical problems, the technical solution of an insect dissecting pen in the utility model is as follows:
[0006] An insect dissection pen comprises a dissection needle, which comprises a needle tip and a dissection needle pen body, and also comprises a dissection pen body with a diameter larger than that of the dissection needle pen body. A clamping head is arranged at the front end of the dissection pen body, and the clamping head comprises a clamping head body and two elastic clamping arms arranged on the left and right. A pen cap is threadedly connected to the front end of the dissection needle pen body at the outer periphery of the clamping head. A push inclined surface is arranged between the inner side of the pen cap and the outer side of the elastic clamping arm to drive the two elastic clamping arms to move relative to each other during the backward movement of the pen cap. A left clamping plate is hingedly connected to the left elastic clamping arm, and a right clamping plate is connected to the right elastic clamping arm. Clamping recesses adapted to the outer periphery of the dissection needle pen body are arranged on the opposite sides of the left clamping plate and the right clamping plate. A dissection needle pen body avoidance space is provided on the clamping head at the rear sides of the left clamping plate and the right clamping plate, and the dissection needle pen body avoidance space is located between the two elastic clamping arms.
[0007] Furthermore, the hinge axis of the left clamping plate and the hinge axis of the right clamping plate are perpendicular to the front-to-back direction and the left-to-right direction, and the axis of the clamping recess is extended along the front-to-back direction.
[0008] Furthermore, a pen body positioning hole is provided at the front end of the clamping head body for the rear end of the dissecting needle pen body to fit and position.
[0009] Furthermore, the inner hole of the pen cap is a tapered hole whose diameter gradually increases from front to back, and the push slope is arranged on the opposite sides of the two elastic clamping arms. The push slope of the left elastic clamping arm gradually extends from front to back toward the left, and the push slope of the right elastic clamping arm gradually extends from front to back toward the right.
[0010] Furthermore, a clamping head positioning groove with its opening facing forward is provided at the front end of the body of the dissecting pen, and the clamping head can be detachably installed in the clamping head positioning groove.
[0011] Furthermore, the rear end of the body of the anatomical pen is threadedly connected with a brush head.
[0012] Furthermore, a lamp bead is arranged at the front end of the body of the anatomical pen on the periphery of the pen cap, a battery electrically connected to the lamp bead through a circuit is arranged on the body of the anatomical pen, and a switch is arranged on the circuit.
[0013] The beneficial effects of the utility model are as follows: in the utility model, a anatomical pen body thicker than the outer diameter of the anatomical needle is provided to facilitate the staff to hold it when using it. However, when faced with a thinner anatomical needle body, how to achieve a reliable connection between the anatomical pen body and the anatomical needle body becomes the key. In the utility model, a clamping head is provided. When the pen cap moves backward relative to the anatomical pen body, the pen cap pushes the two elastic clamping arms to move relative to each other through the pushing inclined surface, and the left clamping plate and the right clamping plate can firmly clamp the anatomical needle body. This is because the left clamping plate is hingedly connected to the left elastic clamping arm, and the right clamping plate is hingedly connected to the right elastic clamping arm. Therefore, the clamping recess of the left clamping plate can be completely fitted with the anatomical needle body, and the clamping recess of the right clamping plate can be completely fitted with the anatomical needle body, ensuring that the left clamping plate, the right clamping plate and the anatomical needle body have a sufficiently large contact area, thereby reliably clamping the anatomical needle body.

[0023] The insect dissecting pen comprises a dissecting pen body 4 with a diameter larger than that of a dissecting needle pen body, a front end of the dissecting pen body 4 is provided with a clamping head positioning groove 17 with an opening facing forward, a clamping head 3 is arranged in the clamping head positioning groove 17, and the rear end of the clamping head is inserted into the clamping head positioning groove from front to back during use, and the corresponding clamping head can be replaced for different types of dissecting needles. The clamping head positioning groove is a square groove, and after the clamping head is inserted into the clamping head positioning groove, the clamping head cannot rotate relative to the dissecting pen body.
[0024] The clamping head includes a clamping head body, and the front end of the clamping head body is provided with two elastic clamping arms arranged on the left and right sides and elastically suspended forward, wherein the elastic clamping arm located on the left is called the elastic clamping arm 13 on the left side, and the elastic clamping arm located on the right is called the elastic clamping arm 14 on the right side. The front end of the dissecting needle pen body is connected with a pen cap 2 through a threaded connection on the periphery of the clamping head, and a push-up slope 12 is provided between the inner side of the pen cap 2 and the outer side of the elastic clamping arm to drive the two elastic clamping arms to move relative to each other during the backward movement of the pen cap. Specifically, the inner hole of the pen cap is a tapered hole with a gradually increasing aperture from front to back, and the push-up slope 12 is provided on the opposite sides of the two elastic clamping arms, and the push-up slope of the left elastic clamping arm 13 gradually extends from front to back to the left, and the push-up slope of the right elastic clamping arm 14 gradually extends from front to back to the right.
