Description

Massaging device Technical Field The present invention relates to a massager that can sandwich a treatment portion such as a user's hand and perform massage or the like. Background Conventionally, a massager, which is a massager for defining a treatment target, particularly for a treatment site of a user has been sold on the market. For example, a lower limb massager that massages lower limbs such as the calf and the foot can be used. In addition, hand massagers and the like have been developed which massage the hands and the like of users. In patent document 1, an example of a hand massager is shown. Prior art literature Patent literature Patent document 1 Japanese patent laid-open publication No. 2020-031792. Disclosure of Invention Problems to be solved by the invention However, if the hand of the user is pushed and massaged by the airbag that is inflated and deflated as in patent document 1, the airbag may excessively press the hand of the user with pain, which may cause discomfort. I.e. not receiving comfortable massage. In addition, the hands (finger, palm, etc.) vary in size, thickness, etc. depending on individual differences. In the device for inserting the finger portion as in patent document 1, for example, when the hand is large, there is a possibility that the finger portion cannot enter or is stopped in the middle and cannot enter completely, and problems may occur before use. However, in hand massage by an operation of a massager (an operation of a person), not only press-in massage but also massage (kneading massage and stretching operation) such as grasping the hand and stretching it in the longitudinal direction is performed, which is very effective. However, the device of patent document 1 cannot perform an extending operation for the hands. In view of the above, an object of the present invention is to provide a massager that can sandwich and perform kneading massage, stretching operation, and the like on a user's hand, and that can be used regardless of the size of the hand, thereby enabling effective massage on the user. Means for solving the problems In order to achieve the above object, the present invention adopts the following means. The massager is characterized by comprising an insertion recess into which a1 st treatment part and a2 nd treatment part connected to the 1 st treatment part can be inserted, a1 st massage part which sandwiches and massages the 1 st treatment part inserted into the insertion recess, a2 nd massage part which sandwiches and massages the 2 nd treatment part inserted into the insertion recess, and a drive part which drives the 1 st massage part and the 2 nd massage part, wherein the 1 st massage part is arranged on the front side, the 2 nd massage part is arranged on the rear side, and the 1 st massage part and the 2 nd massage part perform actions of approaching and separating in the front-rear direction. Preferably, the 1 st massage part and the 2 nd massage part move in directions separated from each other in the front-rear direction in a state where the 1 st massage part sandwiches the 1 st treatment part and the 2 nd massage part sandwiches the 2 nd treatment part, and the 1 st massage part and the 2 nd treatment part are pulled. Preferably, the 1 st massage part has a pair of left and right 1 st massage members facing each other and sandwiching and massaging the 1 st massage part from a left-right direction, the 2 nd massage part has a pair of left and right 2 nd massage members facing each other and sandwiching and massaging the 2 nd massage part from a left-right direction, and the 1 st massage members and the 2 nd massage parts are moved closer to each other in a front-rear direction to reach a predetermined position, the 2 nd massage members are moved closer to each other, and the 1 st massage parts and the 2 nd massage parts are moved apart from each other in the front-rear direction to reach a predetermined position, and the 1 st massage members are moved apart from each other, and the 2 nd massage members are moved apart from each other. Preferably, the massage device includes a rotary shaft that rotates by a rotational driving force output from the driving unit, a 1 st swing conversion unit that converts the rotational driving force of the rotary shaft into a nearly separated reciprocating swing motion to swing the 1 st massage member in a forward-backward-leftward direction, and a 2 nd swing conversion unit that converts the rotational driving force of the rotary shaft into a nearly separated reciprocating swing motion to swing the 2 nd massage member in a forward-backward-leftward direction, wherein the 1 st swing conversion unit and the 2 nd swing conversion unit synchronize the reciprocating swing motion to repeatedly perform the nearly separated swing in the forward-backward direction of the 1 st massage unit and the 2 nd massage unit and the sandwiching and releasing swing in the left-right direction of the 1 st massage member and the 2
