Examples

Referring to fig. 1-3, a butterfly is done a case and is used a pen, including doing a case and using a main part 1, the inside wall of doing a case and using a main part 1 has seted up sliding chamber 103, sliding chamber 103's inside wall sliding connection has writing refill 104, it has installation convex part 105 to cup joint on writing refill 104's the lateral wall, fixed connection's the convex part 105's of installation lateral wall trigger lug 106, trigger lug 106 is semi-cylindrical setting, sliding chamber 103's inside wall has seted up the installation spout, the equal fixedly connected with connecting piece 108 in the upper and lower both sides of installation spout, connecting piece 108 is the square convex block setting.

Further, the method comprises the following steps of; referring to fig. 2, the connecting members 108 are located at upper and lower sides in the case pen body 1.

It should be noted that: the arrangement of the installation projection can ensure that the writing pen core 104 can be prevented from automatically retracting when in use.

Referring to fig. 2-3, the upper end of the pen main body 1 for handling cases is fixedly connected with an anti-lost rope 201, one end of the anti-lost rope 201 away from the pen main body 1 for handling cases is fixedly connected with a fixed mounting head 2, the inner side wall of the mounting chute is slidably connected with a driving member 102, the outer side wall of the connecting member 108 is fixedly connected with an elastic tension spring 107, one end of the elastic tension spring 107 away from the connecting member 108 is fixedly connected to the driving member 102, the outer side wall of the driving member 102 is fixedly connected with a contact positioning member 109, the end of the contact positioning member 109 is in contact with the outer side wall of the mounting convex member 105, and the outer side wall of the pen main body 1 for handling cases is fixedly connected with a protection ring 101.

Further, the method comprises the following steps of; referring to fig. 3, the protective rings 101 are provided on both sides of the case handling pen body 1.

It should be noted that: the upper end of the writing pen main body 1 can be rotated and opened, when the writing pen core 104 retracts, the upper part screw cap can be opened, and the writing pen core can be pressed down for reuse.

The working principle of the butterfly type case handling pen is as follows:

when the pen is used for handling cases, an operator can firstly fixedly install the fixed installation head 2 in a case handling room, then hold the pen body of the case handling pen body 1 with both hands to carry out normal writing, if the user wants to take the pen body to hurt himself or other people, the protection ring 101 on the case handling pen body 1 can well protect the user and avoid injuring other people, if the user wants to take a pen nib to prick the pen body, the force of the person is large, when the pen nib contacts an object or a human body, the pen nib part of the writing pen core 104 can move back and stretch, when the writing pen core 104 retracts, the installation convex part 105 can be driven to retract upwards, and because the force of the person is large, the trigger lug 106 on the installation convex part 105 can be driven to overcome the tension of the elastic tension spring 107, will contact setting element 109 along the radian on its surface and push up, drive the nib and withdraw completely and handle a case with in the pen main part 1 until writing refill 104, at this moment originally trigger lug 106 rear to trigger lug 106 and carry out spacing contact setting element 109 and can remove to trigger lug 106 the place ahead, prevent to write refill 104 through inertia and stretch out once more, it needs to explain, when normally writing, because the dynamics of writing is lighter, so cause the power that writing refill 104 nib contracts in will be less, at this moment under the effect of elasticity extension spring 107 pull force, contact setting element 109 can withstand the ascending that triggers lug 106 completely, avoid being backed out, guarantee that the nib part of writing refill 104 can not take place to contract when normally writing.

It should be noted that the specific model specification of the motor needs to be determined by type selection according to the actual specification of the device, and the specific type selection calculation method adopts the prior art in the field, so detailed description is omitted.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
